' 1 Claim.

This invention relates to men's trousers and particularly to the closuremeans for the front opening thereof. It has been proposed to providesuch openings with a closure of the zipper or slide fastener type insubstitution for buttons and button holes. These slide fastenerscomprise a pair of stringers, each consisting of a tape having a row ofuniformly spaced fastener elements secured thereto and adapted to bein.- terlocked with or disengaged from the elements in the other seriesby means of a slider member. The'tapes are secured together at one endof the series of elements by a bottom stop which serves two purposes,one to keep the slider from slipping off the interlocking elements andtwo to maintain the tapes in such position when the fastener is open,that the elements of one tape are always opposite the spaces between theelements of the other tape.

Trousers as ordinarily constructed comprise four main parts, viz, rightand left back sections and right and left front sections. It is usual inconstructing the garment to stitch together the left back and left frontsections to form one half of the garment and to stitch together theright back and right front to form the other half of the garment. Eachhalf is completed with its part of the waist band, pocket openings, andits section of the fiy, andthe various seams pressed before the halvesof the. garment are stitched together at thecrotch and back seam.

It is necessary, in the manufacture of the trousers to secure thefastener tapes to the fly at of the garment. As the fastenertapeshaveheretofore been secured together at the factoryjit will readilybeapparent that, asconsi'derable finishing of each half of the garmenthas to take place after the tapes are securedto the fly, the other halfof the garment must. be continuously manipulated to keep it .out of theway during the" stitching operation, and further the p'resser foot ofthe sewing machine has to be raised and low-" ered to permit the slideto be manipulated back and forth-in order to enable the stitching tobe'effected sufficiently close to the fastener elements. It will beapparent therefore that the use of a fastenerof this type complicates.and slows down considerably the manufacture of the garment, and it isthe object of my invention therefore to devise a new method ofmanufacturing the garment which willenable' each half of the gar- 'mentto be completed independently-and while entirely unconnectedwith theother half; the two halves after completion being stitched togetheratthe crotch and back scam in a usual way.

Briefly I attain my object by employing two entirely unconnected tapes,each of which has a series of securing elements thereon adapted to bebrought into co-operative relationship with those of the other series,and by separately constructing each half of the garment and in thecourse of said construction securing a separate tape to such half. Aftereach half has been completed, the two halves are stitched together atthe'crotc'h and back. The fastener tapes are then brought together andthe usual slide member slid over the ends of the series of securingelements. After the slide is in place the tapes are finally securedtogether below the securing elements, by stitching or otherwise, toprevent accidental disengagement of the slide member.

The invention is hereinafter more specifically described and illustratedin the accompanying drawing in which I Fig. 1 is a perspective view of apair of trousers with the slide'fastener applied thereto;

Fig. 2 is a front view of the completed halves leg section. 2. Eachsection ,is first constructed as a'separate unit, as shown in Fig. 2,being subsequently joinedby stitching around the crotch and up the backtothe waist, to. form the complete' garment as shown in Fig. 1-'whichalso shows the garment provided with the usual opening at the front. 1It is desired to provide the opening with closure means of the zipper orslide fastener type. I therefore secure to the face of the left, orblack, fly in a'tape 3 having along one edge a 'series'ofuniformly-spaced fastener'members 5 mounted thereonand to the face ofthe right, or white, fly la having along one edge a series of fastenermembers 6 thereon adapted to be engaged with-the members 5. These tapes3 and 4, it will be noted from Figs. 2 and 3, are entirely unconnectedwith one another during the con- ]structionof the respective garmentsections.

Referring to Fig. 3, it will be seen that the right, or white, flyla: isformed as a separate struction comprising a right leg section i and leftpiece provided with an inside facing 8. and the I tape 4 is securedbetween the fly la and the main part I by stitching 8.

As will also be seen from Fig. 3, the front ll of the other part of thegarment is formed inthe other edge to the front in, the other tape I isfirst secured to the face of said fly by stitching I2, one reason forthis prestitching of the tape 3 being to avoid having the stitchingshowon the front of the trousers.

After the parts of the opening have been completed, as well as any otherof the usual operations required in finishing up each garment section,the two main sections are then stitched together around thecrotch and upthe back seam in the usual manner.

After the garment has been thus completed, the usual slide I4 is mountedon the lower ends of the series of fastener members, the method ofapplication being as shown in Fig. 4 in which the slide is shown mountedon the tape 4 and the tape 3 being threaded therethrough. The lower endsof the said tapes I and i are pref-1 erably left unstitched from thegarment to facilihate this threading.

To prevent accidental disengagement of the slide from the fasteners, thetapes immediately adjacent the lower ends of the fasteners are securedtogether in any suitable manner, such as by stitching I5 of any type butpreferably by attaching a bottom stop. The lower ends of the fly willalso then be stitched together at 16 in a usual manner.

It will be seen from the above specification that the fastener tapes areentirely unconnected until the garment is complete, thus permitting thecarrying on of the stitching, seam pressing and other operations withoutany interference from the fastener or the other part of the garment, andthus the manufacture of the garment is materially facilitated.

What I claim for my invention is:

The method of constructing trousers having a front opening closed by aslide fastener which consists in taking the separated mating stringersof a slide fastener which comprises a pair of tapes each having a row offastener members uniformly spaced along its edge, sewing one of saidstringers to the face of one of a pair of trouser flies, sewing theother of said stringers to the'face of the other fly and in suchposition that when the trousers are completed the fastener elements ofone tape will be disposed opposite the spaces between the fastenerelements of the other tape and with the end elements of each rowadjacent one another, sewing one of said flies and its attached stringerto a trouser section, sewing the other of said flies and its attachedstringer to a complementary trouser section, joining the trousersections, threading both fastener tapes through a slider after thetrouser sections are Joined together and thereafter permanently'securingthe tapes together in such position that the fastener elements of onetape are opposite the spaces between the fastener elements of the othertape by attaching a bottom stop to both tapes adjacent the end fastenerelement of the series which is adjacent the crotch of the trousers.
